PTR?

PTR just started downloading what appears to be a full Update, but no announcement.edit: Patch Notes still show 2.6.1.55235 and will not open although it says Playable.Error message says new patch will load, but it doesn't.

I want to clarify that Pain Enhancer, specifically, isn't necessarily the culprit here. However, we have identified an issue with lag that arises primarily at high Greater Rift levels (100+) in 4-man groups. While we sometimes see issues arise in other cases, these high-intensity areas are where the issue appears most reliably.

While we don’t have a current ETA, you may have seen a PTR launch this week that you’re unable to access; that’s because we’re duplicating the live environment to run some of our own tests to hone in on possible solutions. We appreciate all the reports, details, and discussions that have been arising on this issue as it’s already helped immensely in confirming some of our investigations.

Once we have an actionable fix, we’ll follow up with more information. Thanks so much for your patience and understanding while we work to improve your gameplay experience!

Blizzard is supposedly using the PTR for internal testing of various mechanics and must still be ref. the above post....

as long as you are not botting this season, you have little to worry about

The actual download was only about 128 MB. But, you'll see varying amounts when you first run the Blizzard Battle.net App. The first couple of stages are: "Fetching encoding table" and "Fetching download manifest". The patch doesn't start until after you see: "Initializing" on the status bar. And then you'll see "Downloading".

I am able to click the "Play" button, but after the Main Menu loads I get kicked back to the desktop. Obviously, because there is no PTR currently available.
